Job description

Job Summary About the Role:

We’re the Camera Platform team, powering the backend for the video devices in our Smart Home / Connected Living organization. As Smart Home rapidly expands its lineup of connected devices, our charter is growing with it: we’re building the platform that turns 3rd‑party device onboarding from a series of bespoke integrations into a repeatable, scalable capability — enhancing home security and peace of mind for Comcast customers. The work goes beyond connecting any single device: you’ll help build the abstractions and patterns that bring a growing ecosystem of devices online reliably through cloud‑to‑cloud API and event‑driven integrations. This is a Go/AWS‑first role: net‑new development is in Go, and you’ll implement integrations, contribute to the platform patterns the team is establishing, and own components end‑to‑end.

What You’ll Do

• Design and build scalable, high‑concurrency backend services in Go on AWS (Lambda, EC2, DynamoDB, SNS/SQS, SSM).
• Implement integrations with external cloud platforms via APIs and event/callback models — working with auth/token lifecycle, API contracts and versioning, and rate limits — contributing to the frameworks and patterns that make onboarding repeatable.
• Work with core device‑platform concepts — device identity, capabilities, commands, events, state synchronization, and onboarding/deprovisioning — as you build and operate integrations.
• Contribute to mapping device capabilities into our platform, working with technical and business teams.
• Build resilient, event‑driven integrations on top of third‑party systems — handling async event processing, idempotency, retries, partial failure, and state reconciliation.
• Provide maintenance and support for our existing Java/Spring Boot platform during an ongoing transition, while net‑new development is Go/AWS‑first.
• Contribute to performance tuning, reliability, and observability improvements.
• Build and ship using AI‑assisted development tools as part of day‑to‑day engineering.
• Participate in architecture and design discussions.
• Take ownership of features and components end‑to‑end.

Required Qualifications

• 5+ years of backend software engineering experience
• Solid backend engineering skills in a statically typed language such as Java or Go (we are Go‑first going forward; willingness and ability to ramp to Go required)
• Hands‑on experience with AWS cloud‑native services (Lambda, EC2, DynamoDB, SNS, SQS)
• Solid understanding of distributed systems, concurrency, and scalability
• Experience with CI/CD pipelines and GitHub Actions
• Experience operating production services (participating in on‑call, monitoring, incident response)
• Education Bachelor's Degree (Required) While possessing the stated degree is preferred, Comcast also may consider applicants who hold some combination of coursework and experience, or who have extensive related professional experience.
• Certifications (if applicable)
• Relevant Work Experience 5‑7 Years

Preferred Qualifications

• Experience with Infrastructure as Code (Terraform)
• Production Go experience
• Exposure to 3rd‑party API/device integration or IoT
• Experience integrating external cloud platforms or SaaS APIs (auth/token lifecycle, webhooks/callbacks, rate limits)
• Experience with event‑driven architectures and asynchronous messaging (e.g., SNS/SQS, queues, streams, pub/sub)
• Prior IoT or device‑platform experience
• AWS certification is a plus, though hands‑on production experience matters more
• Experience using AI‑assisted development tools
• Strong cross‑functional communication skills
• Experience with Spring Boot or Micronaut
